He died on May 12, according to the coroner's office. Further details about his cause of death were not immediately available.
Fuhrman was convicted of lying on the witness stand in Simpson's trial over three decades ago.
He was one of the first two police detectives sent to investigate the 1994 killings of Simpson's ex-wife, Nicole Brown Simpson, and her friend, Ronald Goldman, in Los Angeles. The slayings and Simpson's trial exposed divisions on race and policing in America.
Fuhrman reported finding a bloody glove at Simpson's home, but his credibility came under withering attack during the trial as the defense raised the prospect of racial bias.
Under cross-examination, Fuhrman testified that he had never made anti-Black racial slurs over the previous 10 years, but a recording made by an aspiring screenwriter showed he had used the N-word repeatedly.
The former detective was charged with perjury and pleaded no contest in 1996. He went on to become a TV and radio commentator and wrote the book "Murder in Brentwood" about the killings.
During Simpson's criminal trial, the prosecution asked him to put on gloves believed to have been worn by the killer, but they didn't appear to fit properly.
Defense attorney Johnnie Cochran famously told the jury in his closing argument, "If it doesn't fit, you must acquit." On Oct. 3, 1995, Simpson was acquitted of all criminal charges.
Simpson was later found liable for the deaths in a separate civil case, and then served nine years in prison on unrelated charges. He died in Las Vegas of prostate cancer in April at the age of 76.
